NCP1568 USB-PD 60W Evaluation board

Overview

TopologyFlyback Converter
Input voltage90-265 V
Switching frequency100-1000 kHz
Output 120 V / 3 A

Description

This design notes describes a 60 W universal input 5 V, 9 V, 12 V, 15 V and 20 V output evaluation board for laptop adapters. This featured power supply is an active-clamp flyback topology utilizing ON Semiconductor’s NCP1568 PWM controller, NCP51530 HB Driver, NCP4305 SR Controller and FDMS86202 SR FET. This design note provides complete circuit schematic, PCB, BOM and transformer information of the evaluation board. It also provide efficiency, transient response, output ripple and thermal data of the evaluation board.

Features

  • Universal AC input operation (90 -265 Vac)
  • High full load and average efficiency
  • Low standby power
  • Very low ripple and noise
  • High frequency operation up to 450 kHz
  • Inherent SCP and OCP protection
  • Thermal and OVP protection
  • Adaptive frequency operation based on AC input and output load conditions
  • Adaptive ZVS operation.
  • Smaller EMI components.
  • Multiple probe points for evaluation
  • Smooth startup operation
